When replacing a hard drive backplane on the DSS 7000, what must you remember to migrate?

When replacing a hard drive backplane on the DSS 7000, it is essential to remember to migrate the light pipes at the front of the backplane. Light pipes are critical for the visual indication of drive status; they allow for LED signals to be transmitted from the drives to the front panel of the system. If the light pipes are not properly migrated during the replacement process, it can lead to a lack of visual feedback regarding the status of the hard drives, causing difficulties in monitoring and diagnosing the operational state of the drives.

Other components, such as power cables or data transfer cables, may have independent connections and may not directly affect the visualization of drive status. Consequently, while those elements might be important in their own right for the overall functionality of the system, the migration of light pipes specifically addresses the necessity of maintaining the visual indicators that users rely on for assessing the health of the storage devices.
